The power of water pump is 4 kW. If `g=10 ms^(-2),` the amount of water it can raise in 1 minute to a height of 20 m is

A

`5xx10^4` L

B

`10^6` L

C

`3xx10^5` L

D

`3xx10^6` L

Text Solution

Verified by Experts

The correct Answer is:
D
P=`(mgh)/(t)=((rhoxxV)gh)/(t)=(Pxxt)/(rhoxxgh)=V`
V=`(5xx10^3xx5xx60)/(10^(-3)xx10xx50)`
`V=(1500xx10^4)/(500)=3xx10^5` L
